Steve, that reminds me the mantra in the chorus line of Genesis' "Carpet Crawlers" ... You've Got To Get In To Get Out ...
In any case, one of the things I point out is that the current baptism vows imposed by the GB upon the baptism candidate may well render such baptism invalid, because
a) On the first question, a demand for a previous "dedication" [enkainia] to Jehovah; that's not part of a Christian baptism.
b) On the second question the part " Do you understand that your dedication and baptism identify you as one of Jehovah's Witnesses ...?" is also wrong, because baptism should identify someone as a Christian; not as a minister of a given religious creed.
c) On the second question "...in association with God's spirit-directed organization" is very problematic because introduces an allegiance to an organization, even an earthly organization, into a vow that should involve ony God, Jesus Christ and the Holy Spirit.
The baptism vows as practised currently within the JWs certainly constitute an ordination as a religious minister, but not a biblical Christian baptism.
